Question

你可以看到我试图用c＃执行两个oracle函数第一个函数F_INS_ORDER_DATA返回值，将作为参数使用第二个但是当第二个函数执行时F_INS_ORDER_DATA_DETAILS我得到的误差

我在蟾蜍中测试这两个功能，它们工作正常，所以

我错过了什么？
如果我的代码有任何改进或更好的方法，我会非常感谢任何建议

Answer 1

Oracle区分过程和函数。

程序存储的代码不返回值。函数是存储返回值的代码。你使用它们的方式（在Oracle中）有点不同。

由于数据库抱怨MyCollection::whereRaw('(updated_at - created_at) < ?', 300)->get();不是一个程序，它可能是一个函数（带有返回值）但是你没有像第一次调用那样捕获它：

F_INS_ORDER_DATA_DETAILS

因此，请确保您使用的是存储过程：

cmd.Parameters.Add(":vORDER_ID", OracleDbType.Int32, ParameterDirection.ReturnValue);

或从函数中捕获返回值。

using (OracleConnection conn = new OracleConnection(connstr))
using (OracleCommand cmd = new OracleCommand(cmdtxt01, conn))
{
    try
    {
        conn.Open();

        cmd.CommandText = cmdtxt01;
        cmd.CommandType = CommandType.StoredProcedure;

        cmd.Parameters.Add(":vORDER_ID", OracleDbType.Int32, ParameterDirection.ReturnValue);

        cmd.Parameters.Add(new OracleParameter(":P_CUSTOMER_ID", OracleDbType.Int32)).Value = TB_CUSTOMER_ID.Text;
        cmd.Parameters.Add(new OracleParameter(":P_ORDER_NOTE", OracleDbType.Varchar2)).Value = TB_ORDER_NOTE.Text;
        cmd.Parameters.Add(new OracleParameter(":P_CREATED_BY", OracleDbType.Varchar2)).Value = "SYSTEM";
        //excute first SP
        cmd.ExecuteNonQuery();
        //get the value
        TB_INVOICE_ID.Text = cmd.Parameters[":vORDER_ID"].Value.ToString();
        int INVOICE_ID;
        // parse return value
        int.TryParse(TB_INVOICE_ID.Text, out INVOICE_ID);

        // now set 2nd SP 
        cmd.CommandText = cmdtxt02;
        cmd.CommandType = CommandType.StoredProcedure;

        foreach (DataGridViewRow Row in DGV_INVOICE.Rows)
        {
            cmd.Parameters.Clear();
            cmd.Parameters.Add(new OracleParameter(":P_ORDER_ID", OracleDbType.Int32)).Value = INVOICE_ID;
            cmd.Parameters.Add(new OracleParameter(":P_PRODUCT_ID", OracleDbType.Int32)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_PRODUCT_ID"].Index].Value;
            cmd.Parameters.Add(new OracleParameter(":P_UNIT_PRICE", OracleDbType.Int32)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_UNIT_PRICE"].Index].Value;
            cmd.Parameters.Add(new OracleParameter(":P_QUANTITY", OracleDbType.Int32)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_QUANTITY"].Index].Value;
            cmd.Parameters.Add(new OracleParameter(":P_DISCOUNT", OracleDbType.Int32)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_DISCOUNT"].Index].Value;
            cmd.Parameters.Add(new OracleParameter(":P_ORDER_STATUS", OracleDbType.Varchar2)).Value = '1';
            cmd.Parameters.Add(new OracleParameter(":P_ITEM_NOTE", OracleDbType.Varchar2)).Value = Row.Cells[DGV_INVOICE.Columns["DGV_ITEM_NOTE"].Index].Value;
            cmd.Parameters.Add(new OracleParameter(":P_CREATED_BY", OracleDbType.Varchar2)).Value = "SYSTEM";

            cmd.ExecuteNonQuery();
        }


    }
    catch (Exception EX)
    {
        MessageBox.Show(EX.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
        return;
    }
}

执行多个oracle函数会返回错误
